Karma is not a very good criterion, it’s too much about participation, and less so about quality. It’s additive. A cutoff of 20 points to post articles seems a reasonable minimum requirement, but doesn’t tell much. The trolls who cause slow suffocation will often have 20 points, while new qualified people won’t. Only extreme values of Karma seem to carry any info, when controlled for activity. Comment rating as feedback signal is much more meaningful.

What about looking at average karma per a comment rather than total karma? That might be a useful metric in general. There may be some people with very high karma that is due to high participation with a lot of mediocre comments. Someone with higher average karma might then be someone more worth paying attention to.
